As others have said: reflog.
I just wanted to add, I've had a lot of luck using reflog's
@{now} feature:
git reflog show @{now}
Coupled with a vague recollection of what action I did at
what time, this has saved me a few times, and if I've been
jumping around branches as well, then:
git reflog show HEAD@{now}
Another good one is:
git show-branch --sha1-name -g=5
(or some larger value depending on how big your xterm is.)
This is particularly useful when I've done a lot of 'git
commit --amend' or rebases; the top most '+' sign in each
column, starting from the left, is your reflog -- I don't
know who came up with this design but it's amazing how much
useful information is condensed into that display.
